LPC4370
32-bit ARM Cortex-M4/M0 microcontroller
P1_18 N12 J10
[3]
I; PU I/O GPIO0[13] — General purpose digital input/output pin.
I/O U2_DIR — RS-485/EIA-485 output enable/direction control for USART2.
- R — Function reserved.
O ENET_TXD0 — Ethernet transmit data 0 (RMII/MII interface).
O T0_MAT3 — Match output 3 of timer 0.
I CAN1_RD — CAN1 receiver input.
I/O SGPIO12 — General purpose digital input/output pin.
- R — Function reserved.
P1_19 M11 K9
[3]
I; PU I ENET_TX_CLK (ENET_REF_CLK) — Ethernet Transmit Clock (MII
interface) or Ethernet Reference Clock (RMII interface).
I/O SSP1_SCK — Serial clock for SSP1.
- R — Function reserved.
- R — Function reserved.
O CLKOUT — Clock output pin.
- R — Function reserved.
O I2S0_RX_MCLK — I2S receive master clock.
I/O I2S1_TX_SCK — Transmit Clock. It is driven by the master and received by
the slave. Corresponds to the signal SCK in the I
2
S-bus specification.
P1_20 M10 K10
[3]
I; PU I/O GPIO0[15] — General purpose digital input/output pin.
I/O SSP1_SSEL — Slave Select for SSP1.
- R — Function reserved.
O ENET_TXD1 — Ethernet transmit data 1 (RMII/MII interface).
I T0_CAP2 — Capture input 2 of timer 0.
- R — Function reserved.
I/O SGPIO13 — General purpose digital input/output pin.
- R — Function reserved.
P2_0 T16 G10
[3]
I; PU I/O SGPIO4 — General purpose digital input/output pin.
O U0_TXD — Transmitter output for USART0.
I/O EMC_A13 — External memory address line 13.
O USB0_PPWR — VBUS drive signal (towards external charge pump or
power management unit); indicates that VBUS must be driven (active HIGH).
Add a pull-down resistor to disable the power switch at reset. This signal has
opposite polarity compared to the USB_PPWR
used on other NXP LPC
parts.
I/O GPIO5[0] — General purpose digital input/output pin.
- R — Function reserved.
I T3_CAP0 — Capture input 0 of timer 3.
O ENET_MDC — Ethernet MIIM clock.
